I play guild wars 2 and I'd like to stream it. Nowadays on my Pi4 steam streaming from my AMD rig works really well. BUT, it doesn't stream an overlay window I use for location markers overlaying on the map. Steam sort of acts as if the game is true fullscreen and not windowed fulllscreen. Can anyone help? I use streaming because I can't always sit at a desk for long periods, but not having the overlay means some tasks aren't really achievable without doing so.

thanks for your suggestions
